Accelerating queries based on zone condition tallies

摘要

Some embodiments provide a non-transitory machine-readable medium that stores a program. The program receives, from a requestor, a query for data comprising a condition on a column of a table. The table includes a plurality of records divided into a plurality of zones. The program further determines a set of zones in the plurality of zones that include records that satisfy the condition based on a plurality of tallies associated with the plurality of zones. Each tally in the plurality of tallies is for indicating whether a zone in the plurality of zones include records with data values in the column of the table that satisfy the condition. The program also determines a result set of records in the table that satisfy the condition based on records in the set of zones. The program further sends the result set of records to the requestor.
